'Unearthed: impacts of the Tellus surveys of the north of Ireland details how this unprecedented land and air survey of hidden Ireland rewards us with a more complete understanding of the natural history of this region. It tells an epic story of how Ireland's geological past will sustain its future'. Professor Iain Stewart MBEBetween 2004 and 2013, million of government and EU funding was spent on high-resolution, airborne geophysical and geochemical sampling surveys of Northern Ireland and the six northern counties of the Republic of Ireland. This book presents some of the findings of the first two stages of Tellus, the largest collaborative cross-border programme of geoscience surveys ever undertaken on the island of Ireland. Tellus is a concerted cross-border investment in the terrestrial geosciences, intended both to stimulate exploration for natural resources and to generate essential data for environmental management. A huge volume of geoscientific data has already been produced and analysed by researchers in Ireland, the UK and beyond. In this book, scientists who have worked with the Tellus data reflect on the outputs and impacts in terms of the economy, the environment, energy, agriculture and ecology.
